No changes have been made anywhere except for the username passed by the
client. All reporting of user names and all administration go by their
full pg_shadow username, so global user dave@ is dave in pg_shadow, and
dave is dave(at)db1 in pg_shadow. One goal of this patch was a small
footprint.

Nope, none of this is done and I don't think there is a demand to do it.
